Guillermo del Toro talks The Hobbit's majestic monsters. A photo reveals a new Doctor Who alien — or is it a familiar face? Plus, Summer Glau speaks riddles on Dollhouse, and news from Shazam, The Green Hornet, Lost, and Supernatural.

Shazam

Screenwriter Bill Birch says that while the Captain Marvel movie will have an edge to it — but it won't be Dark Knight gritty, and will probably have a PG-13 rating. He admitted that Dwayne Johnson could be a possibility for Captain Marvel, given Johnson's relationship with director Peter Segal. Birch says he always saw Ryan Reynolds in the role, but that's out now that Reynolds is playing the Green Lantern. [Cinema Blend]

The Hobbit

Guillermo del Toro will have a cameo as a background monster in the film. He says he'll have a line or two, then die quickly. He says many of the movie's monsters will be majestic, especially Smaug and the Great Goblin. [/Film]

The Green Hornet

Tipster Kyle discovered the Green Hornet crew was filming on Wilshire Boulevard in LA, and snagged a photo and got a good look at the set:

It is an Armed Forces Recruiting center. Inside there are a bunch of low cubicles set up and in the back was a podium flanked by various state and organizational flags. They are hanging up a sign in front (picture attached) for the center as well as a shoe store next door. I'm not sure how the shoe store fits into things, but it's there!

[Thanks Kyle!]

X-Men Origins: Magneto

David Goyer says the script for Magneto is "brilliant," but it's unlikely it'll go to production any time soon, especially if Fox wants to make another Wolverine movie. [MTV]

Robert Pattinson says he's heard the final Twilight movie will shoot in Portland, and in his wildest dreams he'd like to see Portland-based director Gus Van Sant at the helm. [MTV]

Doctor Who

A new behind the scenes featurette for "Waters of Mars" takes us inside the biodome and shows us one of the water creatures. [Blogtor Who]

And shots from a handful of TV magazines offer a little more insight into the episode. [Blogtor Who]

A poster on the Gallifrey Base forums has a solid theory on how "Waters of Mars" will end. Poster the_silver_shade suspects that the Doctor will rescue Adelaide from her fated death, but in order ensure minimal disruption of the timeline, Adelaide will have to take on a new identity and never see or interact with her daughter or granddaughter again. If so, expect it to be a tearjerker. [Gallifrey Base]

We mentioned yesterday that creatures who may or may not be Silurians appear in the eighth and ninth episodes of the new season. Here's an alleged glimpse of one of those creatures. One message-board poster claims, based on hearsay or inside sources, that the episode takes place 15 years in the future, when global warming has greatly reduced the human population and we're searching for a cure. And a new form of energy involves recycling old mines, which disturbs lizards under the ground — and the lizards start eating corpses. Also, something (possibly a spaceship) blots out the sun. Take this, of course, with a grain of salt. But here's that picture. [Gallifrey Base]

Lost

The producers have filled the role of Kendall, previously mentioned as a sharply witty, intellectual beauty who is caught committing corporate espionage. The corporate spy in question will be played by LA Law's Sheila Kelley. [Ausiello]

And the word is that either the bomb did go off at the end of last season or the show will reset with Oceanic Flight 815 landing safely, not both (the explanation is "it's complicated"). But hasn't it already been established that the bomb went off? [E!]

The DocArzt Lost Blog has a virtual tour of Lost's Hawaiian film locations using Google Maps. You can check out the building from which Locke was thrown, where Jin first saw Sun, Hurley's mansion, the spot where Bernard and Rose met, and the Beach Camp. [DocArzt]

Dollhouse

Summer Glau's character has an unsurprising tendency to speak in riddles, but she will make one shocking direct statement, and it will bring us closer to the origin story of one of the show's most important characters. [E!]

Supernatural

Anna will come back in an episode next year, and she'll want to kill Sam so he doesn't say yes to Lucifer. She'll travel back in time to kill Mary and John Winchester (sadly, they'll be "young Mary and "young John," so no Jeffrey Dean Morgan), and Sam and Dean will naturally have to go back and stop her. [E!]

In this week's episode, Ahsoka and fellow Padawan Barriss Offee will embark on a mission to destroy Poggle the Lesser's Geonosian droid factory without their masters. Barriss is Luminara Unduli's Padawan, and Luminara is a very by-the-book master. Barriss takes a similarly structured approach to her duties. But as she spends more time with Ahsoka, Barriss will come to trust her instincts more and we'll see more of her vulnerability and curiosity.

Here's a clip of their daring break in:

V

Morena Baccarin says that the Visitors have emotions, but they're very zen about it and don't get caught up in the drama of things. She also says that the relationship between humans and Vs changes by the fourth episode. [Korbi TV]

Scott Wolf says Chad isn't a shady dude, and that he has a sense of journalistic integrity. He says that Anna is control for the time being, but Chad has a few tricks up his sleeve. [Korbi TV]

Chuck vs. The Terminator? Robert Patrick, former T-1000 and X-Files FBI agent, will appear in the midseason episode "Chuck Versus the Tic Tac." He'll be playing Col. Keller, a mysterious figure from Casey's past. [Ausiello]

Brandon Routh and Kristen Kreuk will be coming between Chuck and Sarah this season. Kreuk's character Hannah shares a kiss with Chuck, and the pair go at it in the Buy More's Home Theater Room. But she's not what she seems. As for Routh's Shaw, he and Sarah will find themselves in a moment of peril where they confess their love for one another. [E!]

Heroes

We'll get to see the young HRG in the eighteenth episode. Here's the casting call:

[YOUNG HRG] 20 Male. Caucasian. Free spirit. Hippie turned used car salesman in the late 70s. Newlywed naively invites a stranger into his home and tragedy ensues. We are looking for someone to play the young version of the actor Jack Coleman sptv050769. CO-STAR / POSSIBLE GUEST STAR/

Peter uses his fancy new healing power on Parkman in the promo for next week's episode, "Brother's Keeper."

And we have the official description for episode twelve, "The Fifth Stage."

Unexpected visitors greet H.R.G.; Samuel's plan starts to come to fruition; struggling to accept the truth, Peter takes extreme measures to get what he wants; Claire's journey leads her to an unexpected destination.

Things will be looking a bit greener in the two-part Justice Society arc in January. Phil Morris' Martian Manhunter will play a role in the first part, "Society," but it's the "Legend" episode where he'll really shine. [Fancast]
